php - 使用 phpmailer 发送表单时没有页面刷新

Question

尝试将 phpmailer 与允许您发送表单而无需刷新页面的功能相结合。通常一切看起来都很好，只是电子邮件没有发送。在有关 phpmailer 的清晰代码上，一切正常。

我希望无需刷新页面即可发送电子邮件。也许有人遇到过类似的问题？

向我显示副标题:“感谢您联系我们，我们会尽快回复您。”但不幸的是邮箱不是空的。

除了 try/catch 问题，您还有其他问题。

SMTPSecure = 'tls' 和 Port = 465 的组合将不起作用；要么更改为 ssl 模式，要么更改 Port = 587。这在故障排除指南中有详细记录。

不要使用提交者的地址作为发件人地址；这是伪造的，会导致您的邮件因 SPF 失败而被退回或被垃圾邮件过滤。将您自己的地址放在表单地址中，并将提交者的地址放在回复中 - 请参阅 PHPMailer 提供的联系表单示例。
